>>1 Alright, you raise valid curiosities.
There are many reasons why a person may begin/continue to cut. I have spoken to many who do, and here are some reasons:
The pain is a distraction
To get high off the endorphins
To "purify" ones self by "spilling the filth from your body"
Force of habit
To attract the sympathetic attention of others
To attain "battle scars" (This weird guy cut his face to look cool)
To attempt suicide
Curiosity about why others do it
"BECAUSE I CAN"
To spite someone who wishes them well-being (The girl was spoiled shitless)
To have something to show others, so they can see the scars cutting leaves behind. As an example of what not to do.
Having some sort of control, even if it's only over their own pain
Self-loathing
Over the last 7 years, these are the reasons I have been given for people that I've met who thought to cut themselves.
